Ok folks I simply do NOT understand this. The firewall seems to be
working fine. Standard NAT (allowing my workstations out) seems to be
working fine. But I am completely unable to get NAT to redirect
incoming requests. This is what I am using:
---------ipf.conf---------

---------ipf.conf---------
---------ipnat.conf---------

rdr iy0 0.0.0.0/32 port 443 -> 192.168.0.5 port 443
---------ipnat.conf---------
If my understanding is correct, the NAT rules get applied before the
packet goes through the IP FIlter. These means that the rules I have
allowing things into 192.168.0.1 will never be used, I simply had them
there to make sure:)
Another question: It is my understanding that when I get a new IP
address for my ISP, I need to have NAT update itself. What is the best
way to do this considering the machine never disconnect?
